Basements in Waterville, OH often deal with hidden water issues, especially in older homes or properties where groundwater pressure builds up behind foundation walls. That was exactly the case for this homeowner, who was in the middle of a basement remodel when their contractor uncovered widespread mold growth and signs of active water intrusion. Production came to an immediate stop, and the homeowner reached out to Toledo Basement Repair for a complete and reliable solution.
Identifying the Problem
When we arrived at the Waterville home, the situation was more severe than the homeowner initially realized. Even though they had already corrected the exterior grading, moisture was still seeping into the basement.
During the remodeling demolition, the contractor noticed mold behind the drywall, staining on the foundation walls, and clear evidence of leaks. Once everything was stripped back to the foundation, it became obvious that this was not an isolated problem. Moisture intrusion was widespread throughout the basement, and mold had developed across several interior surfaces.
The most serious issue, however, was structural. The rear poured foundation wall was bowing inward, a common problem caused by hydrostatic pressure. Left unaddressed, this type of deflection can worsen over time and compromise the home’s integrity. Immediate reinforcement and moisture control were essential.
Crafting the Right Solution
Demolition & Mold Mitigation
We began by safely removing all affected materials, including drywall, studs, firing strips, and any mold-contaminated debris. Nails and fasteners were pulled from the masonry walls to prepare the surface.
Our mold mitigation process included:
Full containment barriers at the crawlspace and work areas
24-hour air scrubbing or negative pressure ventilation
HEPA vacuuming of all surfaces
Application of MMR stain remover
Application of Concrobium Mold Control™ to disinfect and prevent regrowth
Full PPE protection for our mitigation crew
This treatment covered approximately 2,152 square feet, ensuring that the entire basement was safe to rebuild once waterproofing and structural repairs were completed.
Steel Beam Reinforcement
To stabilize the deflecting rear wall, we installed a series of 4-inch I-beams spaced every five feet along the affected 46-foot span. Each beam was:
Installed from floor to joist
Anchored at the top using block-ins at existing joist locations
Set in adjustable floor mounts that allow future tightening if the wall attempts to move
Cracks and joint openings were sealed using Mor-Flex for added structural stability and improved wall performance moving forward.
Full Perimeter GrateDrain™ System
To eliminate moisture intrusion permanently, we installed a full-perimeter GrateDrain™ tile system. This included:
144 linear feet of trenching
GrateDrain tile, clean stone fill, and new concrete
GrateDrain clean-out ports
T ports and EZ Flexi Flange water guides
This system ensures water is captured at the base of the foundation before it can enter the living space, directing it safely to the sump system.
Sump Pump Replacement
We replaced the existing pump with a 1/3 HP Fast Sump system, which included:
Check valve and fittings
Installation into the existing liner
Pumping capacity up to 2400–3000 GPH
A 3-year parts and labor warranty
Full Wall Protection & ThermalShield™ Installation
To provide long-term moisture protection and energy efficiency, we installed ThermalShield™ wall vapor barrier from floor to joist. This 90-mil, fire-rated system:
Blocks moisture
Reflects heat back into the basement
Prevents mold, mildew, and humidity issues
Active Moisture Control
To keep humidity under control year-round, we installed a WiseAire 100 high-capacity dehumidifier capable of removing up to 100 pints of water per day. This system helps preserve structural integrity, improve indoor air quality, and prevent future mold issues.
Delivering Lasting Results
By addressing mold, structural movement, and moisture intrusion at the same time, we delivered a fully restored and protected basement for this Waterville homeowner. The foundation is now stable, the moisture pathway has been eliminated, and long-term humidity control is in place. The homeowner can continue their remodel with confidence knowing their basement is clean, dry, and structurally sound.
